Here are the 50 practical scenarios on how to Create and Configure Local Storage and Filesystems, which are important for the RHCSA (Red Hat Certified System Administrator) exam:
Partitioning and Formatting:
1. Create a new primary partition on a blank disk.
2. Create a new logical partition within an extended partition.
3. Format a partition with the ext4 filesystem.
4. Mount a filesystem to a specific directory.
5. Unmount a mounted filesystem.
6. Check the integrity of a filesystem using the “fsck” command.
Filesystem Operations:
7. Create an empty text file with a specific name.
8. Copy a file from one directory to another.
9. Move a file from one directory to another.
10. Rename a file using the “mv” command.
11. Delete a file using the “rm” command.
12. Create a symbolic link to a file.
13. Create a hard link to a file.
Filesystem Permissions:
14. Change the owner of a file using the “chown” command.
15. Change the group ownership of a file using the “chgrp” command.
16. Modify file permissions using the “chmod” command.
17. Add read and write permissions to a file.
18. Remove write permission from a file for the owner.
Filesystem Quotas:
19. Enable disk quotas on a filesystem.
20. Set a soft quota limit for a specific user.
21. Set a hard quota limit for a specific group.
22. Generate reports on disk usage and quotas for users and groups.
Logical Volume Management (LVM):
23. Create a physical volume (PV) from a disk or partition.
24. Create a volume group (VG) using one or more physical volumes.
25. Create a logical volume (LV) within a volume group.
26. Extend the size of a logical volume.
27. Resize a filesystem to use the new space in a logical volume.
RAID Configuration:
28. Create a software RAID-1 (mirrored) device.
29. Create a software RAID-5 device.
30. Add a new disk to an existing RAID array.
31. Monitor the status of RAID arrays.
32. Replace a failed disk in a RAID array.
Mounting and Automounting:
33. Automatically mount a filesystem at system boot by editing “/etc/fstab.”
34. Mount and unmount a USB drive manually.
35. Configure a filesystem to be automounted when a specific user logs in.
Filesystem Encryption:
36. Create an encrypted filesystem using LUKS (Linux Unified Key Setup).
37. Format an existing partition with encryption.
38. Mount an encrypted filesystem and provide the passphrase.
39. Automatically unlock and mount an encrypted filesystem at boot.
Filesystem Check and Repair:
40. Schedule a filesystem check at the next boot using the “tune2fs” command.
41. View the current filesystem check status and next check date.
42. Cancel a scheduled filesystem check.
43. Manually run a filesystem check and repair using “e2fsck.”
Network File System (NFS):
44. Share a directory using NFS.
45. Configure NFS to allow access only from specific IP addresses.
46. Mount an NFS share on a client system.
47. Export an NFS share read-only to specific clients.
iSCSI Configuration:
48. Set up an iSCSI target on a server.
49. Discover and connect to an iSCSI target on a client.
50. Automatically mount an iSCSI device at boot.
